To all whom z't may concern:

Be it knownthat we, MARY C. OsBonNE and WILLIAM L. OsnoRNE, citizens of the United States, and residents of Chicago, county of Cook, and State of Illinois, represent -that heretofore EUGENE F. OsBoRNE, now deceased, referred to in the accompanying etition, and the within-named WILLIAM L. sBoRNE did jointly invent cert-ainy new and useful Improvements in Joints for Connecting Fittings, (said MARY C. OsonNE having'been duly appointed administratrix to the estate of said EUGENE F. OsnoxNE, deceased, as by reference to a certified copy of letters of administration annexed to the aforesaid petition will more fully appear;) and we, the said MARY C. OsBonNE and WIL- LIAM L. OsBoRNE, do hereby declare the following to be a full, clear, and exact description of said invention, reference being had to the accompanying drawings, and to the reference characters marked thereon, which form part of the specification.

This invention relates to improvements in high pressure joints for connecting fittings `in a piping line, such for instance asvalve fittings, T or elbow fittings andthe like, and the invention consists in the matters hereinafter set forth and more particularly pointed out in the appended claim.

The object of the invention is to provide a simple, compact, economical and eflicient joint, adapted more particularly for use in piping lines for conveying fluids under high pressure, and a joint which may be easily assembled and taken apart.

In the drawings, Figure 1 is an axial section of the adjacent ends of two fittings connected by a joint embodying the invention. Fig. ,2- is an end view of one of the fittings. Fig. 3 is a section of the union ring of the joint.

As show-n in the drawings, 10, 10 desig nate the adjacent ends of two tubular ttings that are adapted to be connected in alinement by the joint embodying the present invention. Said tittin s are provided at their ends with integral iganges 11 `through alined openings in which extend clamping bolts 12 by which the joint making members are' pressed together. Each fitting is provided at its inner end with an annular lip or extension 1 4 surrounding the bore thereof. The said 11p is provided with an interior cylindrical opening 15 and an exterior cylindrie surface 16. The ttings are connected by a union ring which comprises inner and outer cylndric, concentric members 17 and inner member 17 fits closely at its ends in the cyliudric opening 15 and an exterior cylinthe outer, concentrically arranged member 18 fits over the exteriorly cylindric portions 16 of the annular lips 14. The said web portion 19 is arranged midway between the ends of the members 17 and 18 of the coupling ring so as to provide at the ends of the ring spaces 2O to receive packing rings 21, .21 and the inner ends of the lips or extensions 14 of the fittings. Said web ortion as herein shown is made integral w1th the cylindric members 17 and 18. The lips 14 of the fittings constitute the male members of the joint, and the spaces 2O between the inner and outer members 17 and 18 of the union ring constitute the female members of the joint which receives the said lips or male members 14 and the packing rings 21. The packing rings 21, 21 are compressed between the ends of said lips 14 and the annular web 18 of the junction ring, said web constituting a common packing ring abutment for the two packing rings of the joint. The ends of said annular lips 14 are inclined to the diametric plane of the union ring and the sides of the packing ring abutment or web 19 of said ring are oppositely inclined to give to each packing ring recess when the parts are assembled, a generally triangular cross section. The packin rings are of general triangular cross sectIon to fill said recesses so that when the flanged fittings are forced together the tapered sides of the packing rings are acted upon by the opposingly inclined surfaces of the lips 14 and the abutment 19 in a manner to force the packing rings closely on the inner member 17 o f the coupling ring. The said packing rings are surrounded on all sides by metal walls, which prevent the packing rings from flowing unpacking rings and the recess is such as to 18, respectively, and a central web 19. The

der pressure, and the cross section of the produce a particularly tight joint, well vada ted to withstand highipressures.

T is application is a division of the rior application of Eu ene F. Osborneand liam L. Osborne, edJanuary 3,1910, Se? rial No. 535,980.

The joint describedy iel compactl re' quires but little space, is easy t o manufacture and inst-al1 and is very eiclent to produce ak fluid tight joint between the two fitt-ings'connected thereby.

The details of the rconstruction are capa-l ing means engaging the flanges for clamping the fittings together, and provided also at their adjacent ends with annular lips constituting the male members of a joint, of a p Loeaeic arranged to t outside said lips an aninner relatively. .thin ring memberl to.t within said annular li s anda radialabutment, and' packinggrings etween said inner and outer members, -said'lips being vadapted to enter the k annularspaces between said members and to compress the packing rings between the same and said abutment.

In testimony whereof, the foregoingA is claimed as the invention of said EUGENE F. OsBoRNE, deceased, and WILLIAM L. Os- BoRNF., we have aiixed our signatures in the presence of two witnesses this 19th day of May, 1910.
